1. A sensor mounting structure for a vehicle, comprising: a fender panel structuring a side surface of a vehicle front portion; a cowl side panel configured to be provided at a lateral side of a cowl, and disposed at an inner side, in a vehicle transverse direction, of the fender panel so as to face a rear portion of the fender panel; a peripheral information detection sensor disposed at an inner side, in the vehicle transverse direction, of the rear portion of the fender panel and at an outer side, in the vehicle transverse direction, of the cowl side panel, the peripheral information detection sensor having a detection portion that detects peripheral information regarding the vehicle, and the detection portion facing toward an outer side in the vehicle transverse direction; and a mounting bracket having a vertical wall to which the peripheral information detection sensor is fixed, the mounting bracket configured to be fixed to the fender panel or another vehicle body side member at the vehicle front portion and being disposed between the peripheral information detection sensor and the cowl side panel.

2. The sensor mounting structure for a vehicle of claim 1 , wherein: the mounting bracket has an upper wall that extends from an upper end of the vertical wall toward an outer side in the vehicle transverse direction, and the upper wall covers at least a portion of a top surface side of the peripheral information detection sensor, and the upper wall is inclined toward a vehicle upper side on progression toward the vehicle transverse direction outer side from the upper end of the vertical wall.

3. The sensor mounting structure for a vehicle of claim 2 , wherein a rib, which projects out toward a vehicle upper side and extends in a vehicle longitudinal direction, is formed at a vehicle transverse direction outer side region of the upper wall of the mounting bracket.
